Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] see figure 1 , figure 2 A boiler coal bunker anti-blocking device is characterized in that it includes a feeding roller, a transmission shaft 3 and a motor 4, and the feeding roller is installed at the contraction part with a diameter of less than 1 meter under the raw coal bunker 1, and is composed of The motor 4 is driven by the transmission shaft 3 . The two ends of the power transmission shaft pass through corresponding holes on the coal bunker 1. The feeding roller rotates under the drive of the transmission shaft 3, and the blade 2 of the feeding roller stirs the raw coal blocked above during the rotation, so as to dredge it. In order to make the coal bunker anti-blocking device of this boiler conveniently withdraw from the corresponding hole on the coal bunker 1 when it is not working, the blades 2 of the feeding roller are no...

Abstract

In order to solve the original coal bunker blockage problem, the invention provides an anti-blockage device of a boiler coal bunker. The device is characterized by comprising a feeding roller, a transmission shaft and an electric motor; the feeding roller is mounted at the shrinkage position, with the diameter being on meter, below an original coal bunker, and is driven by the electric motor through the transmission shaft, the two ends of the transmission shaft penetrate corresponding holes in the coal bunker, the feeding roller is driven by the transmission shaft to rotate so as to move raw coal blocked above the upper portion, the dredging effect is achieved, furthermore, blades of the feeding roller are not located on the same plane in a staggered manner, when the feeding roller does not work, the roller shrinks into the transmission shaft through a controller connected into the transmission shaft, accordingly, drawing can be conveniently achieved through corresponding holes in thecoal bunker, and the disturbance in the raw coal feeding process is reduced.

Description

technical field [0001] The invention belongs to the technical field of boiler raw coal anti-blocking, in particular to a boiler coal bunker anti-blocking device. Background technique [0002] The blockage of the lower opening of the boiler raw coal bunker has plagued coal-fired power plants for a long time, seriously threatening production safety and production efficiency. Generally speaking, the upper part of the raw coal bunker structure is a cylinder, and the lower part is a hyperbolic cone or other shapes with a large top and a small bottom. The upper port is large and the lower port is small, and the material falls into the combustion chamber of the boiler from top to bottom depending on its own weight. As the falling material flows in the conical container, the more it flows down, the smaller the area is, which forms a greater extrusion on the material itself. The extrusion is transmitted to the silo wall, which increases the external force and probability of the fin...
